Abstract：The direct purpose of wave equation inversion is to solve for P and S-wave veloeities.By using adjoint theory of distributed parameter control system,velocity gradient formulae of P and S-waves can be derived from elastic wave equation;then the numerical inversion is done by adopting optimized iteration technique.Modeling computation produces food result.This method is proved feasible.
